As slicing the deposit down, the problems of blast vibration to the local residents have grown in most surface mining. Previous and general actions for vibration control can be used on a limited scale, and have adverse effect on the mining productivity. For one of efficient solutions, we have developed the new ANFO based on continuously measurement data and computed form of blast vibration in populated areas, and that has the potential advantages of mitigating vibration and keeping productivity. The inner rim presplit blast of the mining area is another solution for the first time in limestone mines and quarries of this country. Those solutions provided 22% mitigated blast vibration results and can help stability and productivity of the mining.
